About this app
What Stackup does
Stackup asks 20 questions about your goals, diet, blood markers (optional), and medications, and proposes a small, defensible supplement stack — drawn from the NIH Office of Dietary Supplements public reference materials, with a built-in drug-interaction checker. It sells nothing. It links nothing. It explains what each pick is for, and tells you when the evidence is thin. What's in v1: — The 20-question intake: goals (energy / sleep / cognitive / cardiovascular / mood / longevity), diet, training load, medications, allergies, recent labs (optional). — Stack proposal: 4–8 supplements with dose, timing, food, evidence rating (Strong / Moderate / Weak), and a 2-line rationale. — Interaction checker: bundled NIH/MedlinePlus drug-supplement interaction table. Flags problematic combos (St John's Wort × SSRIs, magnesium × certain antibiotics, vitamin K × warfarin, etc.). — Re-check: every 90 days, surface a check-in to confirm or change the stack. — Plain-English library: 30 supplements with what it is, what it does, the evidence base, and the dose. Stackup explicitly does not: sell supplements, link to retailers, take affiliate fees, or recommend brand names. It tells you the ingredient + dose + timing — go buy it at any pharmacy. Free. There is no paid tier in v1.

Why it exists
The problem
$160B global supplement market (Grand View Research). 90% of consumers take wrong supplements at wrong doses. Persona Nutrition raised $210M and declined; Care/of acquired then shrunk. The personalized-but-not-brand-tied app doesn't exist.
What's different
How Stackup stands out
Stackup is the only iOS supplement app with NO commerce surface. Persona, Care/of, Vous Vitamin, Athletic Greens are all retailers. Function Health is labs. Stackup is the recommendation only — you go buy the ingredient wherever. Drug-interaction surface is the moat: bundled, fast, in-app.
